The approach to road network development is necessarily different depending on the region in question. This is due to the fact that proper network development practices are dependent on the extent of the network in question, the goals and priorities of the network’s overseers, and the expectations of the commuting public. However, regardless of the scope of a network, recent advancements in network development continue to improve road networks’ affordability, reliability, safety, and environmental impact.
In an area of the world that has had an extensive road network in place for decades, network development would focus on preservation of the existing roadway and maintenance of commuter safety. Advancements in project selection guidelines, innovation of construction materials and practices, and a better understanding of the service life of roadways all contribute to the current status of network development in extensive road systems. It is now known that regularly scheduled, non-intrusive preservation practices provide a cost-effective way of maintaining a road network’s service life that is preferable to a reactive, “worst-first” maintenance schedule. Managers of road networks are devoting more resources to preservation practices because such network development practices are more affordable, are less environmentally intrusive, and they present less of an inconvenience to commuters.
However, in an area of the world with a less extensive road network, the priorities and goals for network development would be entirely different. For example, a road network consisting of a large amount of unpaved roads would have little interest in pursuing preservation practices. Instead, development of such a system would consist of prioritizing roadways based on their level of use, selecting an affordable and appropriate paving method, and determining the optimal location of new roadways in order to maximize civic utility and efficiency.
Regardless of which end of the spectrum of network development a region falls, the road system will undoubtedly play an integral role in questions of civic planning and societal development. In an under-developed area, a road system will provide the first steps toward improved infrastructure. Phone, television and internet service, construction projects, improving civic services such as electricity and waste disposal, etc. All of these civic services rely heavily on road systems. The sooner a society is able to acquire a reliable road network, the sooner they will be able to make advancements in other areas of urban development. For advanced systems, network development is looking forward by prioritizing preservation projects, turning toward greener practices and materials, and investigating new advancements in commuter safety such as integrating infra-red technology into roadways for improved visibility in bad weather conditions. Network development remains an important civic concern regardless of the level of complexity of a road system.
Spoke and Hub Approach
The design of inter-city or international road alignments using the spoke and hub approach involves creating a network of primary road connections that radiate outward from central hubs or major cities. The Key aspects of Spoke and Hub approach are:
- Identify Major Hubs
- Establish Primary Spokes
- Consider Traffic Volumes and Demand
- Plan Interchanges and Connections
- Develop a Secondary Road Network
- Consider Geographical Constraints
- Coordinate with Regional and International Networks
- Safety and Infrastructure Standards
- Multi-Modal Integration
- Long-Term Planning and Future Expansion
The major cities or hubs should be determined within the region or country that will serve as the central points for the road network. These hubs are typically chosen based on factors such as population, economic activity, geographic location, and connectivity to other modes of transportation like airports or seaports.
Primary road alignments or spokes that connect the major hubs to each other should be designated. These primary spokes act as the main arteries of the road network, facilitating efficient and direct transportation between the major cities. The alignment of these primary spokes should be carefully planned to optimize travel distances, minimize congestion, and consider geographical features and existing infrastructure.
Traffic volumes and travel demand patterns should be analyzed to determine the appropriate number of primary spokes and their capacity, assessing factors such as projected population growth, economic development, tourism, and freight movement, considering the volume and types of vehicles that will utilize the road network to ensure it can handle anticipated traffic.
Interchanges and connections where primary spokes intersect or meet major highways should be planned. These interchanges allow for smooth transitions between routes, efficient traffic flow, and access to secondary roads. Proper interchange design should consider safety, capacity, and ease of movement for vehicles.
A secondary road network should be developed, that complements the primary spokes and connects smaller cities, towns, and regions to the major hubs. The secondary roads typically branch off from the primary spokes and provide access to areas that are not directly served by them. These roads should be designed to accommodate local traffic and provide connectivity to the primary network.
Geographical constraints should be considered such as mountains, rivers, or protected areas when designing road alignments, assessing the feasibility of constructing tunnels, bridges, or bypasses to overcome these obstacles and ensure efficient travel routes.
The design of the road network should be coordinated with regional or international transportation networks, such as transnational highways or border crossings, ensuring that road alignments are connected seamlessly to these networks to facilitate cross-border travel and trade.
Adhering to safety standards and best practices is vital in road design, including factors such as alignment, signage, lighting, road markings, and pedestrian facilities, considering the appropriate number of lanes, median barriers, and shoulders based on traffic volume and anticipated growth.
Multi-modal integration should be planned at major hubs, incorporating interchanges, bus terminals, train stations, or other modes of transportation. This allows for seamless transfers and improved connectivity between different modes of travel.
The long-term planning should be engaged to account for future growth and changes in transportation needs, anticipateing the potential need for future expansions or upgrades of the road network to accommodate increased traffic demand or changing travel patterns.
